The Alimentary Canal The alimentary canal, or digestive tract, is where food travels and is broken down and absorbed. It is made up of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus. The wall of the alimentary canal consists of four layers, although their characteristics may vary from one organ to another. The innermost lining of the alimentary canal is the mucous membrane, or mucosa. It is a protective layer that may have invaginations that are used for the secretion of mucus and enzymes. Some areas of the mucosa have projections or folds that increase the surface area of the canal for better absorption.

Remind students to be careful throughout this stage since the coloring cannot be removed.
